Title: Constant current power source circuit
Inventor: KOYASHIKI TORU
IPC: G05F1/56
Filed: 1993-08-06
Abstract: PURPOSE:To prevent the occurrence of excess voltage in output even if a load resistance becomes infinite by connecting a Zener diode between the base of a first transistor and a voltage detection circuit. CONSTITUTION:A transistor 21 is operated so that current flowing in a resistance 16 becomes constant when the resistance value of a load 4 is small. When the resistance value of the load 4 becomes large, and the sum of voltage at the both ends of the resistances 19 and 16 is higher than the sum of the threshold voltage of the transistor 21 and the drop voltage of the Zener diode 22, current flows through a resistance 20, the Zener diode 22 and a resistance 17, and it becomes signal current flowing into the base of the transistor 21. The signal current and the transistor 21 are amplified and it is transmitted to a main circuit 2 through a photocoupler 9. Since the current value flowing in the photocoupler 9 becomes large as the resistance value of the load 4 becomes larger, the output voltage of a constant current power source circuit is controlled to become small.

Filed: 1981-12-07
Abstract: PURPOSE:To realize prompt and certain turnabout of a linear article with directivity by slidably providing a turnabout bar in a horizontal part of a turnabout hopper for said article in the longitudinal direction so as to cut across said horizontal part. CONSTITUTION:An article (a) discharged at each weighing is thrown into a collecting hopper 12 by means of a bucket 17, and an opening or closing lid 14 is opened to discharge said article into a turnabout hopper 1. The article (a) thrown herein is reversed due to its hitting at a turnabout bar 8 simultaneously with its entry into the horizontal part 2, and moved to a vertical part 3 along a tapered face 4, then aligned on standby in vertical attitude on an opening and closing plate 10, subsequently being supplied to a packing machine through opening of said plate 10. Since the turnabout bar 8 is formed arc-like in its middle part, dropping articles can be not only reoriented almost without a time lag at the bar 8 but also collected in the central direction of reaction actuated by hitting without dispersion. Accordingly, turnabout and alignment can be performed certainly and promptly, and an article of different length can also be handled because the bar 8 is slidable.

Abstract: PURPOSE:To process the main surface of a wafer by forming a hermetically sealed chamber through free attachment or release of processing vessel to/from the stage allowing free placement of wafer and then supplying the processing gas into the chamber and then exhaust it therefrom. CONSTITUTION:After preprocessing, a wafer 4 is carried in and placed on the surface 3 of a stage 1, the stage 1 is moved upward 2 and engaged with a vessel 22. Thereby, a hermetically sealed chamber 23 is formed by a sealing ring 9. Thereafter, a valve 18 is switched and exhausts a chamber 23 to a vacuum condition 15, and a valve 34 is switched. Thereby N2 is injected into a tank 27 and generated processing gas is supplied to the chamber 23. The valve 18 closes and the valve 20 opens. Thereby, the processing gas is gradually exhausted from a hole 10 and the chamber 23 is kept in the fresh and constant ambient. The processing gas in the contact with the wafer decomposes water content and thereby intensifies bonding characteristic with the resist. After a constant period, a valve 34 is switched and thereby supply of N2 is suspended, residual gas is released 35 and supply of processing gas is suspended. Thereafter, the stage 1 moves downward, releasing the chamber 23. Accordingly, the wafer 4 can be delivered. With such structure, a constant processing quality can be ensured and working efficiency can also be improved.

Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of bending and vibration of a shank by a bending force by a method wherein a small shaft part is protruded from a large shaft part and a stepped space is formed throughout the whole of the outer periphery of the small shaft part. SOLUTION: In the lower end part of a shank 1, a small shaft part 3 is protruded from the lower end face 4 of a large shaft part 2 to form a stepped space 9 throughout the whole of the outer periphery of the small shaft part 3. The diameter D1 of the large shaft part 2 except the small shaft part 3 to which each grinding wheel 10 is adhered is sufficiently larger than the diameter (d) of the small shaft part 3 in a range wide enough to prevent the occurrence of a trouble to actual grinding. Thus, by increasing rigidity of the shank 1, vibration owing to bending and vibration by a bending force hardly occurs to the shank 1. Each grinding wheel 10 performs a function to fill the stepped space 9, and breakage of the small shaft part 3 is prevented from occurring through prevention of production of a rapid change from the large shaft part 2 to the small shaft part 3.
